摘要:采用桑枝为原料制备磺化化机浆（SCMP浆），考察磺化条件对桑枝SCMP浆性能的影响。通过单因素实验和响应面分析法探讨制备SCMP浆的最佳工艺条件。结果表明，最佳工艺为：NaOH用量3%，Na²SO³用量18%，最高温度115℃。在此条件下获得的SCMP浆白度为49.4%，耐破指数为4.51 kPa·m²/g，抗张指数为31.8 N·m/g, 撕裂指数为5.35 mN·m²/g。

Abstract:The effect of sulfonation conditions on papermaking performance of SCMP using mulberry stalk as a raw material was studied. The optimal bleaching conditions of was obtained by using single factor experiment and response surface methodology. The dosages of NaOH and Na²SO³ were 3% and 18% respectively and maximum temperature was 115℃. The brightness, burst index, tensile index and tear index of the bleached pulp were 49.4%, 4.51 kPa·m²/g, 31.8 N·m/g and 5.35 mN·m²/g.
